Lt. Roy Mulcahy asked me to provide you with the information you
requested by email. Please understand that the information stored and
used on the ALPR is till ultimately governed by the Executive Office of
Public Safety and their Highway Safety Division. We do not disseminate
or use the data (other than purely raw data- statistical numbers such as
how many plates it views, etc...) in any other way, similar to the
process that we submit a query to NCIC/LEAPS via a computer terminal.

Below are the answers to the questions you posed:


The use of LPR systems is restricted to public safety-related missions
of this agency. LPR systems and associated equipment and databases are
authorized for official public safety purposes.

official public safety use.

outside of the actual system. No data, except raw results (number of
queries, number of alerts, number of "hits", etc...) is collected or
reviewed. Actual information such as personal information is not stored,
collected or reviewed.

Extent and timeline for ALPR data storage:

Data is only stored in the computer to which the ALPR is attached. It is
only available for the time that the information can be viewed. Raw data
is available as stated above.

Protocols and Extent data is shared.

Data is only shared for legitimate law enforcement purposes and nothing
else. Only Raw data, pure statistical numbers, is provided to EOPSS

time to meet if that would work better. Either way, please do not
hesitate to ask.
